Expand description
Post-processing: complex arithmetic, discrete Fourier transforms,
port analysis (power waves, S-parameters) and SAR (sar).
Sign convention used throughout ems: a time signal x(t) is mapped to
the frequency domain with the kernel e^{-j2πft}, i.e.
X(f) = ∫ x(t)·e^{-j2πft} dt (engineering convention, j² = -1). The
discrete transforms in dft approximate this integral, and
Waveform::spectrum evaluates it
analytically.
